摘要:
用可对气溶胶粒径切割的采样器采集了太原市中心1985年冬季的大气气溶胶样品。以X射线荧光法分析出的化学元素作为变量,对数据作了因子分析、标示元素多元回归处理。结果指出,粒径小于2.5μm的细粒子中约有76.5%来自燃煤排放出的SO2转化成硫酸盐,约13.5%来自建筑石料高温烧结;2.5—15μm之间的粗粒子中约有82.8%来自燃煤排放出的煤飞灰;在TSP范围内,混合尘与燃煤两类源的贡献率分别是41.6%和45.2%。源识别结果表明太原市冬季气溶胶主要来自煤炭燃烧,而石油化工、金属冶炼及汽车尾气等源的贡献很小。工业粉尘、基建扬尘、路面及自然风沙等类型的源,主要在大粒径范围内(TSP)才有贡献。 就燃煤源而论,工业用煤对气溶胶(飘尘部分)污染的贡献约是居民用煤的11.8倍,因此,研究解决工业燃煤造成的大气污染是一个主要问题。 "

Abstract:
The Samples of aerosol were collected by Series 245 Automatic Dichotomous Sampler and High volume Air Sampler during the period of January 15 - 30 , 1985 in Taiyuan, and 17 elements were analyzed by X-ray fluorescence To identify the emission sources of air pollutants , factor analysis was used . Through application of multiple regression analysis , the contribution of several sources to the aerosol might be estimated .The model indicates that 76.5% of fine particles ( aerodyncmic size < 2.5μm) repre ents Sulphate formed in gas-to-particle conversion of SO2 , it may come from coal combustion and 13.5% of fine associated with the sintering process of limestone silicate, bauxite and so on . In the coarse particles (between 2.5 - 15 μm ), about 82.8 % was coal flyash , In the TSP , about 41.6 % and 42.2% was due to mixed dust and coal combustion respectively . These results show the aerosol in winter of Taiyuan comes mainly from coal combustion , especially for industrial uses.
